Auxiliary Raw Materials for Aluminum Casting

At Transformación Puebla, we commercialize a complete catalog of auxiliary raw materials essential to the aluminum casting industry. From our base in San Pedro Cholula, Puebla, we distribute silicon metal, master alloys compliant with the EN 575 standard, and pure alloying metals to foundries, extruders, and metallurgical companies throughout Mexico, with competitive pricing and consistent availability.

Silicon metal is the primary alloying element in most aluminum casting alloys. At Transformación Puebla, we offer four grades covering different purity levels and applications: grade 5505 (maximum iron 0.5%, maximum aluminum 0.5%), widely used in standard casting alloys; grade 3303 (maximum iron 0.3%, maximum aluminum 0.3%), popular for medium-purity alloys; grade 2202 (maximum iron 0.2%, maximum aluminum 0.2%), for more demanding applications; and grade 1502 (maximum iron 0.15%, maximum aluminum 0.02%), for high-purity alloys where trace control is critical. We currently offer special pricing on grades 3303 and 5505, the most requested grades in the Mexican market.

Master alloys compliant with the European EN 575 standard are fundamental metallurgical additions for controlling the microstructure of molten aluminum. We commercialize the following master alloys: AlTi10 (aluminum-titanium at 10%), used as a grain refiner to achieve a fine, uniform crystal structure that improves mechanical properties; AlTi5B1 (aluminum-titanium 5%, boron 1%), the most efficient grain refiner thanks to the presence of TiB2 particles that act as heterogeneous nucleants; AlSr10 (aluminum-strontium at 10%), a silicon-aluminum eutectic modifier that transforms silicon morphology from acicular needles to a fibrous structure, dramatically improving ductility and impact resistance; and AlSr15 (aluminum-strontium at 15%), a more concentrated version of the modifier for processes requiring a lower addition rate.

We complement our offering with pure alloying metals: magnesium ingot, used to increase the mechanical strength of Al-Si-Mg alloys such as A356 and 6061 through precipitation hardening (Mg2Si); electrolytic manganese in flakes or pieces, employed to improve corrosion resistance and to neutralize the negative effect of iron on mechanical properties; and titanium compact at 80%, an economical alternative to AlTi wire for grain refinement in high-volume heats.

All our raw materials come with manufacturer analysis certificates and are stored under controlled conditions at our San Pedro Cholula plant. Our technical team can advise you on the appropriate dosages for your process, the type of alloy you produce, and the metallurgical results you seek. Whether you need a single shipment or a continuous supply program, at Transformación Puebla you will find the backing of over 35 years of experience in the Mexican aluminum industry.

We have the flexibility to handle orders ranging from small quantities to industrial volumes, and our strategic location in central Mexico allows us to deliver efficiently to customers nationwide. Request your quote and discover our competitive pricing, especially on Silicon Metal 3303 and 5505.
